There are several examples of evidence that support endosymbiosis theory. Mitochondria and chloroplasts contain their own small supply of DNA, which may be remnants of the genome the organelles had when they were independent aerobic bacteria.

JACKSON -- A 5-foot, 10-inch baby giraffe named Mika was born at Six Flags Great Adventure earlier this month, becoming the ninth giraffe in the park's Safari Off Road Adventure, park officials said Tuesday.
No. Mammals are divided into three infraclasses: monotremes, marsupials, and placental mammals. A giraffe is a placental mammal. This means that the baby is born live, and that it is born developed enough that it will not have to immediately crawl onto the mother's nipple and attach itself. In fact, baby giraffes can walk seconds after being born.
